Full Idea
The view that all quantification is substitutional is not very plausible in general. Some uses of quantifiers clearly seem to have the function to make a claim about a domain of objects out there, no matter how they relate to the terms in our language.
Gist of Idea
Quantification can't all be substitutional; some reference is obviously to objects

A Reaction
Robust realists like myself are hardly going to say that quantification is just an internal language game.
